Hello there Tere, welcome to my contest! Your options are so different from each other, so I guess it´s better if I comment one by one...
#70 is interesting, would love to see the opposite, with a light background.
#69 I liked that you used the color to fill in in the middle and give the idea of a flower, nice concept.
It would be great if you could give me options of these 2 with less lines if possible, simplify the design.
#67 and # 68 have an unique shape, but I don´t think i have identified myself with it, sorry!
#64 again I like the use of color, but i am afraid it´s not an unique concept, looks too much like a flower and I feel i have seen it before, sorry!
#63 i have definetely seen a lot of this flower in logos before, so not what i am looking for. But I like the concept of a globe/mandala-like shape containing a flower inside.
#61 I liked it a lot how you organized the name and slogan with the symbol. But the symbol can´t simply be a flower, too obvious.
Hope I was clear, feel free to ask questions. Looking forward to seeing your new stuff.
Thanks
Renata
#62 looks really cool, i loved how you used the colors! But i think i need less of them and thinner lines if you could re-work that it would be great!
